No. 1: Singapore

The 21st-century successor to 15th-century Venice, this once-impoverished island nation now boasts an income level comparable to the wealthiest Western countries, with a per-capita GDP ahead of most of Europe and Latin America. Singapore Airport is Asia’s fifth-largest, and the city’s port ranks as the largest container entrepot in the world. Over 6,000 multinational corporations, including 3,600 regional headquarters, are located there, and it was recently ranked No. 1 for ease of doing business.
